How to Make Mac Turn Off or On Automatically

That’s possible, I was referring to the link from @dialabrain which referred only to wake & sleep. It also contained a dead link to pmset, unfortunately.

Irrespective, here’s the pmset command with all the options, should work (prepend sudo):

pmset schedule [cancel] {sleep | wake | poweron | shutdown | wakeorpoweron}
               "MM/dd/yy HH:mm:ss" [owner]

      pmset repeat cancel

      pmset repeat {sleep | wake | poweron | shutdown | wakeorpoweron}
               weekdays "MM/dd/yy HH:mm:ss"
               Where weekdays is a subset of MTWRFSU ("M" and "MTWRF" are valid strings)
